Abstract: 1425674 Anti-skid modulators DBA SA 15 May 1974 [6 June 1973] 21497/74 Heading F2F An anti-skid device for a hydraulic braking system of a vehicle comprises control means 44 for generating at least one control signal when an incipient skidding condition of at least one wheel 48 of the vehicle is detected, a hydraulic pressure modulator comprising a housing 19 containing a modulation chamber 24 capable of being connected to a set of brake actuators 12 for the vehicle and also capable of being connected to a pressure source, i.e. a master cylinder 10, by way of a non-return valve 28 disposed in an inlet passage 14 communicating with the chamber 24 and a plunger 22 slidable in the housing between first and second limit positions corresponding respectively to maximum and minimum penetration of the chamber by the plunger. The latter has one extremity 34 projecting into the chamber for maintaining the valve 28 open when the plunger is in the first limit position and the plunger is susceptible of moving by way of a driving assembly adapted to be operated by the control means 44 so as to permit variation of the braking pressure in the brake actuators. The driving assembly comprises a mechanical transmission including a cam 36 driven by an electric motor 40, angular motion of the cam in a given direction being associated with motion of the plunger in a corresponding given direction, wherein angular motion of the cam in the opposite direction causes motion of the plunger in the opposite direction, the rotation being controlled by the signal generated by the control means. As shown, in Figs. 1 and 2 switches 50, 52 co-operate with stops 54, 56 on the cam 36 when the plunger is in the positions thereof corresponding to minimum and maximum penetrations into the chamber 24 and in which positions a roller 38 on the plunger engages one or other of two recesses 58, 60 in the cam. In a modification, (a) the plunger 122, Fig. 6, is acted upon by a pivoted lever 204 working in a slot 216 of the plunger and having a transverse projection with a roller 212 cooperating with a track 202, or a groove, in the cam 206, (b) the plunger may be formed by part of a torus and is rotatable about the axis thereof, or may have linear motions during the course of which the effective cross-sections vary. An electronic anti-skid logic system, Fig. 3 (not shown), comprising the control device 44 and connected to the sensors 46 of the vehicle's wheels is described.

Title: Process for the manufacture of new sulphurised derivatives of phenols
Filed: 1931-07-31
Abstract: Metalliferous thio derivatives of phenols are obtained by treating products prepared by treating phenols (other than those containing nitrogen) with aldehydes or sulphur halides, with basic reacting substances and metallic compounds or metals of the hydrogen sulphide, ammonia or ammonium sulphide qualitative analysis groups, together with sulphur in those cases where the phenol derivative does not already contain sulphur.  The phenol derivatives referred to above may be dioxydiphenylmethane derivatives obtained by treating phenols with formaldehyde, or dioxydiphenyldisulphides obtained by using sulphur chloride. Resorcinol, and phenols containing alkyl, halogen, sulpho and carboxylic groups are also specified as parent materials. According to examples, (1) commercial xylenol is treated with hydrochloric acid and formaldehyde, followed by caustic soda, sulphur and stannous chloride, to give a yellowish-olive dry product; (2) phenol is treated with hydrochloric acid and formaldehyde, followed by sulphur, stannous hydroxide and caustic soda, to give a blueish-grey powder; (3) phenol is treated with sulphur chloride, followed by caustic soda and stannous chloride; metallic tin may also be employed; (4) phenol is treated with powdered sulphur and chlorine, followed by caustic soda and stannous chloride, to give a grey-brown product; (5) and (6) describe the use of acetaldehyde and benzaldehyde, and chromium hydroxide and stannous chloride respectively, the other ingredients being the same as above, to give brownish products. More highly sulphurized derivatives are obtained by adding sulphur to the melt.  The tin compounds may be replaced by compounds of chromium, antimony, arsenic, zinc, molybdenum, aluminium, manganese, cobalt, and nickel.  The products are suitable for mordanting, tanning and reserving.  The Specification as open to inspection under Sect. 91 (3) (a) refers also to the use in the above process of phenol derivatives obtained by treating phenols with ketones, e.g. acetone.  This subject-matter does not appear in the Specification as accepted.

Patent GB-1131517-A (GB)
Title: Improvements in or relating to moldable fabrics
IPC: D06N3/00
Filed: 1966-05-18
Abstract: 1,131,517. Plastics/fabric laminates. HERCULES Inc. 18 May, 1966 [18 May, 1965], No. 22196/66. Heading B5N. A mouldable fabric comprises a laminate of a thermoplastic film and a backing fabric which contains polypropylene and cellulosic fibres in a ratio of polypropylene to cellulosic fibres within the range of from 2:1 to 20:1 by weight. The cellulosic component may be included in the backing fabric as a component of a composite yarn of blended staple fibres in the ratio 70- 90% polypropylene and 30-10% cellulosic. Alternatively the cellulosic component is in the form of unblended strands interwoven or knit with the polypropylene component. The backing fabric may be a woven or knit fabric or a chemically or mechanically bonded non-woven fabric. To produce the mouldable fabric a film of thermoplastic material is preheated above its softening point and then passed through heated calender rolls under pressure together with the backing fabric. Alternatively the thermoplastic film is melt extruded on to a running length of backing fabric and then calendered, or the film and backing fabric are secured together by adhesive. The laminated fabric may be embossed either by using embossing rollers after joining the backing fabric to the film or by using engraved moulds in the moulding step. The moulding may occur in unheated or heated moulds with the fabric being preheated in the former case and optionally in the latter case. In one example the fabric is clamped loosely in the frame of a compression mould; is heat shrunk until it becomes taut in the frame, and then moulded. In the examples given a plain weave backing fabric containing 91% polypropylene fibres and 9% rayon or cotton fibres is heat set at 300‹ F. This fabric is then calendered to a film of p.v.o. at 215‹ F. In another example a jersey knit fabric of 80% polypropylene/20% cotton composite yarn is laminated to a vinyl film and then moulded to form a typewriter case. The thermoplastic films may be of polyvinyl chloride, polyethylene, polypropylene, cellulose acetate, or a copolymer of vinyl chloride with vinyl acetate or vinylidene chloride. A second thermoplastic layer may be applied to the opposite side of the backing fabric by sprinkling powdered thermoplastic material, e.g. polyethylene or polypropylene, on the backing fabric in the mould prior to preheating. Upon being heated the thermoplastic material melts and forms a mouldable film. The mouldable fabrics of the invention can be used as book covers or in upholstery and are scuff resistant, durable and moisture resistant.

Title: Improvements in or relating to methods of batching textile fibres
IPC: D01G29/00
Filed: 1959-06-29
Abstract: 867,624. Knitting-machines. BARROIS, C. June 29, 1959, No. 22235/59. Class 74 (2). Thread F passing to the knitting point picks up and is dressed by oil as it passes along a groove 11 or 36 in a member 1, which may be generally cylindrical, Fig. 1, or of crescentic form, Fig. 4. The oil is fed to the bottom of the groove by a duct 12 or 37 and capillary ducts 13, 14, or 38, 39. The member 1 is secured to supporting rods 18 of the knitting machine. The cylindrical form has thread lead-on and lead-off portions 16, 15 of reduced diameter. In the arrangement of Fig. 4, the thread passes under one or more light washers 43, threaded on a stud 41 and which are constantly wet with batching oil, the thread being thereby impregnated and tensioned. A hole 42 in the pin permits passage of the thread. The oil is supplied from a reservoir 20, via a constant level vessel 22, a pipe 23, an electromagnetic valve 24, a pipe 25 incorporating an air cock 26, a distributer 27 and flexible pipelines 28, to the members 1. The pressure-drop across wicks 30 in the pipe-lines 28 allows the use of a relatively high pressure in the system upstream of them; and thus the effect of discrepancies in level between the different members 1 is reduced. The valve 24 is actuated by the stop motion or machine clutch and closes if the machine stops. A by-pass 29 facilitates quick filling of the arrangement when the machine is re-started.

Abstract: 642,679. Non - contact - making relays. MINISTER OF SUPPLY. Aug. 11, 1947, No. 22239. [Class 40 (iv)] [Also in Group XL (c)] The Figure shows a magnetically-controlled D.C. amplifier in which oscillator 47 has a very low noise and even harmonic content (see Group XL (c)). Potentiometer 48 is adjusted so that in the absence of a D.C. input at 42 the currents from oscillator 47 balance out and no output appears across the high Q resonant circuit 52 which is tuned to the second harmonic of the oscillator frequency. When a.D.C. input is applied at 42 the ferro-magnetic cores 45, 46 are polarized and second harmonic components produced. These are applied via the transformer 52, 53 and the amplifier 54, which is sharply tuned to the second harmonic frequency, to the phasesensitive detector stage 55 to which an input is also applied from the oscillator 47 via a frequency doubler stage 57 and an amplified D.C. output at terminal 56 is produced which is proportional to the D.C. input at terminals 42.
